We recently added a link to the Journal ofConstitutional History/Giornale di Storia Costituzionale.
Here's some additional information on the journal:
The Journal is a biannual publication. It was first published in 2001 with the aim of promoting and gathering research and methodological proposals that concern the manifold paths of constitutional history. The articles here published intend to analyse – in a multidisciplinary and comparative perspective – the foundations and characters of a complex historical and cultural phenomenon which is the source of a common inheritance, yet with different forms and conceptions. Between present and past, the scholars of law, politics, institutions, and more generally the experts of social sciences think and dialogue about constitutionalism, marked by deep historical roots and growing tensions. The Journal is the only paper magazine dedicated to constitutional history. It has already become a meeting and reference point for the different practices of constitutional history. It publishes essays in various languages and is characterised by thematic richness and variety in surveys, alternating miscellaneous issues with others dedicated to monographic research.
